well we were just kids chasing lizards out behind speedway park,just off the back of sandia base in a place we called hidden valley. and we looked up saw this huge cigar/cylinder shaped thing hanging up in the air .it was grey in color and did'nt make any noise and looked like a blimp sort of but, it was a lot skinnier than any blimp i've ever seen and it scared the hell out of all three of us. we took off running back to sandia base where we lived and, when i looked back after running to the side of the canyon ,it was tearing straight up into the sky and had become vertical. when we saw it at first it was just hanging there horizontally. we did'nt tell our parents or anyone else about it then because we were all army dependents and were not supposed to be over there off base and we were scared to death .i have told a couple of people since but it still gives me a chill whenever i think about it so i try not to.
